Lizards are not particularly smelly pets. If you keep lizards in your home and notice a strong smell, chances are his habitat is not being cleaned properly. That could be because his habitat contains feces and urine or food that's not taken away after a few days and is starting to rot.
Use the Right Products
A number of products, such as Natural Chemistry Healthy Habitat, can help to clean and disinfect small animal environments, including reptile habitats. These products contain no irritants and are biodegradable, so they're safe to use on a regular basis. When shopping for a pet-safe cleaner, look for one that contains natural enzymes, which break down odor-causing bacteria and eliminate contaminants.
Another thing that impacts smell is the type of substrate or flooring you use. This depends in part of the type of lizards you have, as some prefer sand while others do better with earthy substrates. For smaller lizards, you can also choose carpet liners, which can be washed regularly to eliminate any waste smell and then reused. Some types of substrate include nonabrasive, natural deodorizers that will help to keep the smell away for longer periods of time.
Cleaning Frequency and Techniques
Some tanks only need a deep cleaning once a month, while others might need weekly cleanings to remain odor free. However, to keep odors to a minimum, you should remove feces and uneaten food on a daily basis to prevent bacteria from growing and causing odors. If you have soft bedding -- such as sand or soil -- scoop out daily any areas that are soaked with urine. Water dishes should be washed at least once a week, but if you see any food or feces in the water dish, wash it immediately. This will prevent E. coli and other dangerous bacteria from reproducing.
When you are ready for a deep cleaning, remove the lizards and place them into a safe holding container or a second tank so they're not exposed to the cleaning products. Remove everything from the tank before you start spraying and cleaning the tank itself.
Using a commercial product, dish detergent or a mix of vinegar and water, spray the sides and floor of the tank or cage and clean thoroughly using a hard sponge. Use a putty knife to remove any hardened feces or other solid material. If the smell is particularly strong, let the cleaning solution sit on the glass or cage for about 10 minutes before rinsing it off.
Either let it air dry or use paper towels to make sure everything is dry before adding clean substrate and all furnishings and decor, which should be cleaned and dried before being returned to the cage.
